Additionally, when recognizing a selection of a certain application in the application list through the input unit 150, the information inputting unit 171 may determine whether the mobile device 100 is currently connected to any AP through the Wi-Fi module 132. If so, the information inputting unit 171 controls the display unit 160 to display connection information about the connected AP and, when recognizing proximity to or contact with the NFC tag 200 through the NFC module 131, inputs identification information about the selected application, a web address to be accessed, and connection information about the connected AP into the NFC tag 200.

If the mobile device 100 is not connected to any AP, the information inputting unit 171 controls the display unit 160 to display an input window for receiving connection information about APs. The information inputting unit 171 receives AP connection information in the input window from the input unit 150 and, when recognizing proximity to or contact with the NFC tag 200 through the NFC module 131, inputs identification information about the selected application, a web address to be accessed, and the received AP connection information into the NFC tag 200.

In still another exemplary embodiment, the information inputting unit 171 performs a connection with any AP through the Wi-Fi module 132 and, when recognizing that a menu item for the registration of an electronic device is selected in the tag menu through the input unit 150, controls the display unit 160 to display a list of electronic devices coupled to the currently connected AP. The information inputting unit 171 recognizes a selection of a certain electronic device in the list through the input unit 150 and, when recognizing proximity to or contact with the NFC tag 200 through the NFC module 131, inputs connection information about the currently connected AP and identification information about the selected electronic device into the NFC tag 200.

Additionally, when recognizing a selection of the electronic device registration menu item in the tag menu through the input unit 150, the information inputting unit 171 may control the display unit 160 to display an input menu for AP connection information and electronic device identification information. The information inputting unit 171 receives AP connection information and electronic device identification information from the input unit 150 and, when recognizing proximity to or contact with the NFC tag 200 through the NFC module 131, inputs the received AP connection information and electronic device identification information into the NFC tag 200.

The information reading unit 172 reads information from the NFC tag 200. According to exemplary embodiments of this invention, the information reading unit 172 may read Bluetooth device connection information, such as a BD_ADDR and a PIN code, or Wi-Fi device connection information, such as an SSID, a security type, and a password. Additionally, the information reading unit 172 may read, from the NFC tag 200, identification information about an application to be executed and a web address to be accessed. In this case, the information reading unit 172 may further read, from the NFC tag 200, connection information about an AP to be connected. In some exemplary embodiments of this invention, the information reading unit 172 may read, from the NFC tag 200, connection information about an AP to be connected and identification information about an electronic device to output data.

The function performing unit 173 performs a function on the basis of information read from the NFC tag 200. If the information reading unit 172 reads connection information about a Bluetooth device from the NFC tag 200, the function performing unit 173 performs a connection with the Bluetooth device according to the read connection information. Also, if the information reading unit 172 reads connection information about a Wi-Fi device from the NFC tag 200, the function performing unit 173 performs a connection with the Wi-Fi device according to the read connection information.

In another exemplary embodiment, if the information reading unit 172 reads, from the NFC tag 200, identification information about an application to be executed and a web address to be accessed, the function performing unit 173 executes the application according to the read identification information and accesses a web server through the mobile communication unit 110 or the Wi-Fi module 132 according to the read web address. If the information reading unit 172 further reads connection information about an AP, the function performing unit 173 may perform a connection with the AP by controlling the Wi-Fi module 132 according to the read connection information, execute the application according to the read identification information, and access a web server through the AP connected according to the read web address.

In still another exemplary embodiment, if the information reading unit 172 reads, from the NFC tag 200, connection information about an AP and identification information about an electronic device, the function performing unit 173 performs a connection with the AP by controlling the Wi-Fi module 132 according to the read connection information, searches for the electronic device according to the read identification information, and transmits prescribed data to the electronic device.

FIG. 3 is a flow diagram illustrating a method in which a mobile device performs a function by using an NFC tag in accordance with an exemplary embodiment of the present invention.

Referring to FIG. 3, the information inputting unit 171 inputs information related to the execution of functions (hereinafter, also referred to as function-related information) into the NFC tag 200 by controlling the NFC module 131 in step 301. Function-related information may vary according to the function to be performed by the mobile device 100 and may include connection information about a Bluetooth device to be connected, connection information about a Wi-Fi device to be connected, identification information about an application to be executed, a web address of a web server to be accessed, identification information about an electronic device to output contents being currently executed, and the like. While the NFC module 131 is in a state of proximity to or contact with the NFC tag 200, the information inputting unit 171 inputs function-related information into the NFC tag 200. A more detailed process of step 301 will be described later with reference to FIGS. 5, 7, 9, 12 and 13. The NFC tag 200 into which information is input is attached to a certain place or device.

In step 302, the control unit 170 recognizes, through the NFC module 131, that the mobile device 100 is in proximity to or contact with the NFC tag 200. More specifically, when a user brings the mobile device 100 in proximity to or contact with the NFC tag 200 attached to some place or device, the NFC module 131 detects proximity to or contact with the NFC tag 200, creates a detection signal, and sends it to the control unit 170. The control unit 170 receives the detection signal from the NFC module 131 and hence recognizes proximity to or contact with the NFC tag 200.

In step 303, the information reading unit 172 reads function-related information from the NFC tag 200 by controlling the NFC module 131. In step 303, the information reading unit 172 may read Bluetooth device connection information, such as a Bluetooth address and a PIN code, or Wi-Fi device connection information, such as an SSID, a security type, and a password. In another exemplary embodiment, the information reading unit 172 may read, from the NFC tag 200, identification information about an application to be executed and a web address to be accessed. In this case, the information reading unit 172 may further read, from the NFC tag 200, connection information about an AP to be connected. In still another exemplary embodiment, the information reading unit 172 may read, from the NFC tag 200, connection information about an AP to be connected and identification information about an electronic device to output data. The information reading unit 172 sends the read function-related information to the function performing unit 173.

In step 304, the function performing unit 173 performs a function correlated with the function-related information that is read by the information reading unit 172. If the information reading unit 172 reads connection information about a Bluetooth device from the NFC tag 200, the function performing unit 173 performs a connection with the Bluetooth device according to the read connection information. Also, if the information reading unit 172 reads connection information about a Wi-Fi device from the NFC tag 200, the function performing unit 173 performs a connection with the Wi-Fi device according to the read connection information.

If the information reading unit 172 reads, from the NFC tag 200, identification information about an application to be executed and a web address to be accessed, the function performing unit 173 executes the application according to the read identification information, and accesses a web server through the mobile communication unit 110 or the Wi-Fi module 132 according to the read web address. If the information reading unit 172 reads, from the NFC tag 200, connection information about an AP and identification information about an electronic device, the function performing unit 173 performs a connection with the AP by controlling the Wi-Fi module 132 according to the read connection information, searches for the electronic device according to the read identification information, and transmits prescribed data to the electronic device. A more detailed process of step 304 will be described later with reference to FIGS. 8, 10 and 14.

FIG. 4 is a block diagram illustrating a system for offering a specific service in which a mobile device is connected to a selected Wi-Fi device or Bluetooth device through an NFC tag in accordance with an exemplary embodiment of the present invention.

Referring to FIG. 4, the system includes the mobile device 100, the NFC tag 200, a Wi-Fi device 300, and a Bluetooth device 400. According to an exemplary implementation, the system of FIG. 4 may include both or one of the Wi-Fi device 300 and the Bluetooth device 400.

The mobile device 100 and the NFC tag 200 in this system correspond to those shown in FIG. 2, respectively, and a description of the same will be avoided hereinafter.

The Wi-Fi device 300 may be composed of an AP 301 and a Wi-Fi mobile device 302.

The AP 301 corresponds to a base station that supports a wireless access and network connection of the mobile device 100. The AP 301 is connected to a service provider server through a gateway and allows a wireless communication between the mobile device 100 and a service provider server.

The Wi-Fi mobile device 302 has a Wi-Fi module and performs a Wi-Fi based communication with the mobile device 100. The Wi-Fi mobile device 302 is connected to the mobile device 100 through the Wi-Fi Direct. Namely, the mobile device 100 and the Wi-Fi mobile device 302 perform their respective search processes, select the Group Owner, and then perform a Peer-To-Peer (P2P) communication.

The Bluetooth device 400 has a Bluetooth module and performs Bluetooth communication with the mobile device 100. Using a BD_ADDR and a PIN code, the mobile device 100 performs a connection with the Bluetooth device 400.

In the system of FIG. 4, the mobile device 100 inputs Bluetooth device connection information, such as a BD_ADDR and a PIN code, or Wi-Fi device connection information, such as an SSID, a security type, and a password, into the NFC tag 200. Thereafter, when detecting proximity to or contact with the NFC tag 200, the mobile device 100 performs a connection with the Wi-Fi device 300 or the Bluetooth device 400 according to the Bluetooth device connection information or the Wi-Fi device connection information stored in the NFC tag 200.

FIG. 5 is a flow diagram illustrating a process of step 301 shown in FIG. 3 in connection with FIG. 4 according to an exemplary embodiment of the present invention.

Referring to FIG. 5, the information inputting unit 171 recognizes that a tag menu is selected among main menus through the input unit 150 in step 501. In exemplary embodiments of this invention, the main menus of the mobile device 100 contain the tag menu that corresponds to an application for reading a short-range communication tag (e.g., the NFC tag) or for inputting information into the short-range communication tag.

FIG. 15 shows screenshots of a display screen in connection with FIG. 5 according to an exemplary embodiment of the present invention.

Referring to FIG. 15, frame [a] shows a home screen in which a plurality of main menu icons are arranged and the tag menu is assigned to one of them.

Referring again to FIG. 5, after recognizing a selection of the tag menu through the input unit 150, in step 502, the information inputting unit 171 recognizes that a menu item for the registration of a Bluetooth or Wi-Fi device is selected in the tag menu through the input unit 150. More specifically, when the tag menu is selected, the information inputting unit 171 may control the display unit 160 to display menu items in the tag menu. As shown in frame [b] of FIG. 15, the menu items in the tag menu may include a menu item for Bluetooth or Wi-Fi device registration, a menu item for data synchronization, and a menu item for electronic device registration. The menu item for Bluetooth or Wi-Fi device registration is used to input, into the NFC tag 200, connection information about a Bluetooth or Wi-Fi device to be automatically connected by the mobile device 100. The exemplary embodiment shown in FIG. 5 is based on the assumption that a user selects the menu item for Bluetooth or Wi-Fi device registration among menu items of the tag menu.

After the menu item for Bluetooth or Wi-Fi device registration is selected, in step 503, the information inputting unit 171 determines whether any Bluetooth or Wi-Fi device is currently connected through a Bluetooth module (not shown) or the Wi-Fi module 132.

If it is determined in step 503 that there is a connected Bluetooth or Wi-Fi device, in step 504, the information inputting unit 171 controls the display unit 160 to display a list of the connected Bluetooth or Wi-Fi devices. Here, under the control of the information inputting unit 171, the display unit 160 may display a Bluetooth name, a Bluetooth address, etc. of the Bluetooth device or an SSID, a security type, etc. of the Wi-Fi device.

Frame [c] of FIG. 15 shows a list of Bluetooth or Wi-Fi devices currently connected. In frame [c] of FIG. 15, ‘4370’ corresponds to a Bluetooth name and ‘iptime-rula’ corresponds to an SSID.

In the list of currently connected Bluetooth or Wi-Fi devices, a user may select a desired device to be automatically connected. After a user's selection, in step 505, the information inputting unit 171 recognizes the selected device through the input unit 150.

In step 506, the information inputting unit 171 controls the NFC module 131 to determine whether proximity to or contact with the NFC tag 200 is detected. More specifically, a user brings the mobile device 100 in proximity to or contact with the NFC tag 200 so as to input device connection information into the NFC tag 200. Alternatively, a user may bring the NFC tag 200 in proximity to or contact with the mobile device 100. Thereafter, when the NFC tag 200 is approaching within a given distance from the mobile device 100 or touched with the mobile device 100, the NFC module 131 detects proximity to or contact with the NFC tag 200, and thereby the information inputting unit 171 recognizes proximity to or contact with the NFC tag 200.

In step 507, the information inputting unit 171 controls the NFC module 131 and thereby inputs connection information about the selected device into the NFC tag 200. Therefore, the NFC tag 200 stores connection information about a Bluetooth or Wi-Fi device to be connected. In addition, a user may attach the NFC tag 200 to a desired place or device. For instance, if a user wants a Bluetooth or Wi-Fi connection with a selected device at a desired place, he or she may attach the NFC tag 200 to that place. Also, a user may attach the NFC tag 200 directly to a specific device selected for a Bluetooth or Wi-Fi connection.

In contrast, if it is determined in step 503 that the mobile device 100 is not currently connected to any Bluetooth or Wi-Fi device, in step 508, the information inputting unit 171 controls the display unit 160 to display an input window for receiving Bluetooth or Wi-Fi device connection information.

Thereafter, in step 510, the information inputting unit 171 determines whether proximity to or contact with the NFC tag 200 is detected. More specifically, when the NFC tag 200 is approaching within a given distance from the mobile device 100 or touched with the mobile device 100, the NFC module 131 detects proximity to or contact with the NFC tag 200, and thereby the information inputting unit 171 recognizes proximity to or contact with the NFC tag 200.

In step 511, the information inputting unit 171 controls the NFC module 131 and thereby inputs the received device connection information into the NFC tag 200. Therefore, the NFC tag 200 comes to store connection information about a Bluetooth or Wi-Fi device to be connected. In addition, a user may attach the NFC tag 200 to a desired place or device.

Thereafter, as discussed above, the control unit 170 recognizes proximity to or contact with the NFC tag 200 through the NFC module 131 in step 302 of FIG. 3, and, in step 303, the information reading unit 172 reads Bluetooth device connection information or Wi-Fi device connection information from the NFC tag 200. In step 304, the function performing unit 173 performs a connection with the Bluetooth or Wi-Fi device according to the read connection information. In this step, the function performing unit 173 searches for the Bluetooth device according to Bluetooth address information and performs a connection procedure according to PIN code information. Also, the function performing unit 173 searches for the Wi-Fi device according to SSID information and performs a connection procedure according to security type information and password information.
